Which versions of QuickBooks can I export to?

You can import financial data from Wild Apricot to a IIF file that can be imported into QuickBooks 2002 or later. QuickBooks Online does not itself support IIF files, but there are some 3rd party tools (e.g. from Intuit and AaaTeX) that might help you accomplish this. Note, however, that we cannot guarantee the effectiveness of these tools.
